A man police say has left his graffiti tag, "Watch,'' on public buildings in several area towns, has been arrested for the fourth time.

Matthew Cashman, 22, of Wallingford, was charged with 12 separate counts of criminal mischief after his arrest by West Haven police on Monday. Cashman had been arrested a year ago in North Haven, Wallingford and New Haven for the same offense, said West Haven police spokesman Brett Schneider.

"In Wallingford he destroyed an unfinished hotel off of Exit 15 on I-91,'' Schneider said.

The suspect is being held on a $40,000 total bond. No arraignment date was available Tuesday.
